| 中文摘要 | a novel triptycene-based dianhydride, 1,4-bis[4-(3,4-dicarboxylphenoxy)]triptycene dianhydride, was prepared from 4-nitro-n-methylphthalimide and potassium phenolate of 1,4-dihydroxytriptycene (1). the aromatic nucleophilic substitution reaction between 4-nitro-n-methylphthalimide and i afforded triptycene-based bis(n-methylphthalimide) (2), which hydrolyzed and subsequently dehydrated to give the corresponding dianhydride (3). a series of new polyimides containing triptycene moieties were prepared from the dianhydride monomer (3) and various diamines in in-cresol via conventional one-step polycondensation method. most of the resulting polyimides were soluble in common organic solvents, such as chloroform, thf, dmac and dmso. the polyimides exhibited excellent thermal and thermo-oxidative stabilities with the onset decomposition temperature and 10% weight loss temperature ranging from 448 to 486 degrees c and 526 to 565 degrees c in nitrogen atmosphere, respectively. the glass transition temperatures of the polyimides were in the range of 221-296 degrees c. the polyimide films were found to be transparent, flexible, and tough. the films had tensile strengths, elongations at break, and tensile moduli in the ranges 95-118 mpa, 5.3-16.2%, and 1.03-1.38 gpa, respectively. wide-angle x-ray diffraction measurements revealed that these polyimides were amorphous. |
